Well I have news. JoTech dug into this issue for my problem and discovered that a tooth is missing off the reluctor wheel attached to the backside of the new Z1 Lightweight Flywheel. They are going to evaluate the possiblity of welding it back on against the reliability of the welded tooth. I asked them if a new flywheel is needed, and they have not gotten back to me on that question. I'm sure Z1 will want to know that one of their flywheels had a failure of this type. Maybe they'll even cover the failure with a new one. Fingers crossed on that one.
I'll update this thread again when I know more.
My opinion at this point is check your car's flywheel for damage if you have this P0335 issue. In my case I have a new flywheel, so the shop looked there first.

I got the car back from JoTech yesterday. It's all better now. A new Mid-Weight flywheel from Z1 fixed this issue for me. Many thanks to
JoTech and Kevin, Tony, Seth and Christian for their hard work and diligence. The flywheel and missing tooth are out and the new Mid-Weight Z1 Flywheel is in. What a difference this 21 pound flywheel makes. It is smooth and quiet. It revs better in my opinion than the lightweight unit. My guess is that the 370Z engine likes a bit of weight on the crank in order to rev smoothly and stay relatively quiet. The P0335 code is gone now. This broken tooth was the direct cause of the poor running and failure to rev smoothly.
I hope none of you run into this issue with your 370Z, but perhaps my experience and photo essay can help you identify and/or clarify this issue for your P0335 code
Here are photo's of the damaged flywheel and the missing tooth:
